APPARATUS FOR THECONCENTRATIONOR SEPARATION OF ORES.

SPECIFICATION forming part of Letters Patent No. 518,082, dated April 10, 1894.-

Applioation filed November 6,1893. Serial No. A90,l89. (No model.) Patented in South Australia June 21, 1893, No. 2,518, and in New South Wales June 22,1893, No- 4,477.

To all whom it may concern.

Be it known that we, MORTIMER STUOKEY,

agent, and HENRY ARTHUR, mining engineer, subjects of the Queen of Great Britain, residing at Adelaide, South Australia, have invented an Improved Apparatus for the Concentration or Separation of Ores, (for which patents have been granted in South Australia, No. 2,513, dated June21, 1893, and in New South Wales, No. 4,477, dated June 22, 1893,) of which the following is a full, clear, and exact description. r i

Our improved apparatus is based upon the principle that if bodies of equal size, but of differing specific gravities are projected simultaneously in a direct line into still air from the same point, with the same degree of momentum, they will fall at varying distances from the point of departure, according to their respective specific gravities.

Our improved apparatus for concentrating ore or effecting its separation from the gangue consists of a wheel or disk revolving verticallyand provided with transverse vanes or ridges set at a suitable angle. I The crushed dry ore having-previously been reduced to av uniform fineness is fed onto this revolving wheel or disk from a hopper'provided for the purpose, and is thrown forward in a direct line into a closed chamber provided with a series of bins set one behind the other upon an inclined plane. The-particles of ore and gangue being thrown forward in one direction into such a chamber with equal momen tum fall into the several bins of the series, according to their respective specific gravity, 2'. e., the heaviest particles are thrown into the bin at the greatest distance, and so on according to the specific gravity, the lightest or gangue, falling into the bin nearest to the revolving wheel or point of departure.

In order that our invention may be the better understood, reference may be had to the accompanying drawings, in which- Figure 1. is a side sectional elevation of apparatus complete. Fig.2. is a side sectional elevation of the wheel or disk. Fig. 3. is an end sectional elevation of the same.

Similar letters of reference indicate corresponding parts in all figures.

A, is a hopper into which the crushed and graded dry ore is fed from the screens or other source of supply. B concentrating sloping front in order to wholly or partially inclose the concentrating wheel or disk B. D, D, D, series of bins or receptacles secured to a strong'framework and set upon an inclined plane. D D' ore chutes leading from the bottom of the hoppersD through the side of the chamber 0. E rails or slides for carry.- ing the framework of the bins D D, so that the series can be moved backward or forward in the chamber according to the class of ore under treatment.

The manner of effecting concentration or separation by means of our invention is as follows:Dry ore having first been reduced to a uniform degree of fineness is fed intothe hopper A, and falls through a chute provided for the purpose upon the periphery of the the vanes ledges or projections B it is thrown forward ina direct line with uniform momen- 1 tum into the chamberO. This chamber being closed on all sides and the air therein free from outside atmospheric influences the par ticles of ore and gangue are carried forward in the one direction, as shown bythe lines in the drawings, by the momentum received from the revolving wheel or disk B, and fall into one or other-of the bins D, according to their respective specific gravities. Thus, supposing sulphide silver lead ores are being treated, the bin at the greatest distance from the revolving wheel or point of departure will'receive the particles of galena, the next in. the

series a proportion of zinc blende, and so on until the hopper nearest the revolving Wheel receives practically clean gangue. From the several hoppers D, the separated ore falls through the chutes D and is removed for further treatment.

In the working of the apparatus, it is necessary that the number of revolutions per minute of the wheel B shall be regulated according to the grade and class of ore under treatment; the greater the number of separations required, or the finer the grade of the ore, the higher the momentum reqnired,that the ore itself shall be as far as possible dry and re duced to a suitable fineness of uniform grade,-and that the concentrating chamber shall be free from outside atmospheric influences.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what We claim is An ore separating apparatus comprising a chamber, the Wheel B arranged to receive the material and throw it into the chamber the series of hoppers inclining upwardly from the centrifugal wheel and adjustable in inclined position toward and from theisame, and the horizontal Ways along which the series of hoppers is moved whereby the inclination thereof will be maintained, substantially as described.

In witness whereof we have hereunto set our hands in presence of two witnesses.
